Application filed May 22, 1903. Serial No. 158,263.

To all 11-71072] if 712/171] concern:

Be it known that we, DAVID (J. STORE, a citizen of the United States,and a resident of the city, county. and State of New York, and JO- SEMILUIIINO, a subject of the King of Italy, residing in the city and countyof New Haven and State of Connecticut, havejointly invented certain newand useful Improvements in Ad ustable Supports for Sofa-liedsteads or tothe Like; and we do hereby declare the 'following specification.whentaken in connection with the accompanying drawings, to be a full, clear,and exact description of the same, and which drawings represent, in

r5 Figure 1, a side view with the adjustable or movable member down;Fig. 2, an end view of Fig. 1; Fig. 3, a side View of the device whenthe movable member is raised. the dotted lines indicating the positionof the parts when the support has passed over the switch member: Fig. 1,a side view of the support in the act of passing the switch. Fig. 5 is aview of the gravity-actuated switch member.

This invention relates to an improvement in the adjusting device of thepatent to Luppino, No. 721,901, whereby the necessity of i and enablethe stud to pass freely over it. It i was also found that the switch wasliable to stick, especially if it had been painted or varnished. It isthe purpose of our present invention to obviate these diilicultics andsimplify the structure, so that it can be cheaply and econmnicallymanufactured and assembled by workmen of ordinary skill.

In the drawings the device is shown as applied to a metal bedstead ofthe type known movable part is still further lifted, as shown as thedrop-side couch, which has a main frame and extension sides pivotedthereto. it is obvious that the structure can be applied to Morrischairs, to the heads of invalid- 5 beds, to the side leaves of tables,and for like purposes. The frame of these couch-beds is usually made ofL or angle iron, and it is so illustrated in the drawings. 1 is theupright leg, having the front face 21 and the back face 20. 2 is thehorizontal end piece, the parts 2 and 3 forming the fixed member of thesupport. To the horizontal part 2 the swinging or movable member #1 issecured at the point Pivotcd to the swinging member a the supporting baror brace 6 is secured at the point 5. This brace 6 passes through aguide 8 in the front face 21 of the upright 1. At or near its free end anotch 7 is cut to engage the lower face of the guide and hold themovable member 4 in a horizontal position when it is raised. At a shortdistance in the rear of the notch T a stud 8 is secured to the. brace(5, which projects toward the rear face 20 of the upright 1. Secured tothe inside of the back face 20 is the switch shown in Fig. 5. Thisswitch, as shown in Fig. 5, consists of a horizontal upper face 17 and avertically-depending lower part 16. It is pivoted to the rear face ofthe upright at 15, so that the preponderance of weight is in front ofand below the pivot 15, whereby the upper face 17 is normally heldagainst the front face 21 of the upright 1, as shown in Fig. 1, butwhich is capable of yielding to the up- 30 ward movement of the stud 8,as shown in Fig. 1, so that the latter can pass and ride over it. Thefront edge of the switch is so curved that the ends limit the motionabout the pivot 15.

The operation of the device is as follows: The outward end of the mo'able part A: is lifted to a horizontal position, as shown in Fig. 3,carrying the support 6 through the guide 8 until the notch 7 falls intothe bottom 9 of the guide 8. The movable part 1 is thereby lirmlysecured in a horizontal position. To automatically release the notch 7from its engagement with the bottom of the guide 8, so the movable parta may be lowered, the

in the dotted lines in Fig. 3, when the projecting stud 8 strikes thefront face 21 and travels upward along it, throwing the switch to oneside until it has passed the top face 17 Fig. 4 shows the stud in theact of passing the switch and clearly explains the operation. When thestud 8 has cleared the upper face 17 on its upward movement, the switchfalls forward, closing the path of the stud, so that the latter slidesdown over the face 17, while the notch 7 is carried past the guide 8without engaging therewith, and the movable part 4 is thereby permittedto fall into a vertical position.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. An adjustable support comprising a relatively stationary uprighthaving a guide in it, a movable part pivotally secured to the uprightand a notched part pivotally secured to the movable part with its freeend extending through the guide, said notch engaging the bottom of theguide on the upward movement of the movable part, a switch having ayielding horizontal face carried by one of said parts, and a stud on theother part; the stud and switch cooperating on the continued upwardmovement of the movable part to lift the horizontal face of the switchand permit the stud to pass along it thereby carrying the notch out ofengagement with the bottom of the guide.

- 2. An adjustable support comprisingafixed part having a guide in it, aswitch carried by said fixed part and having a yielding horizontal facein juxtaposition to the guide, a movable part pivotally secured to thefixed part,-

a notched brace pivotally secured to the movable part and passingthrough the guide and having at or near its notched end a stud adaptedto engage the switch and pass over the hori- Zontal face on a continuedupward movement of the movable part thereby carrying the notch out ofengagement with the bottom of the guide.

3. An adjustable support comprising a fixed part of L-shapedcross-section having a slot in its front face and an upwardly-movableswitch secured to the back face, a movable part pivotally secured to thefixed part and a brace pivotally secured to the movable part and passingthrough the slot in the fixed part, a notch near the end of the braceadapted to engage the bottom of the slot when the movable part israised, a stud near the notched end of the brace adapted to ride up thefront face of the fixed part on the further upward movement of themovable part and pass the switch whereby the notch will be carried pastthe bottom of the slot without engaging it.

In testimony whereof we have signed our names in the presence of twosubscribing witnesses.
